result_type b() const;

Parameters: This method do not accepts any parameters.

Return Value: This method return the ‘b’ parameter in the distribution, which is the upper bound or the maximum possibly generated value in this uniform_real_distribution.


// C++ code to demonstrate
// the working of b() function
#include <iostream>
// for uniform_real_distribution function
#include <random>
using namespace std;
int main()
    double a = 10, b = 20.5;
    // Initializing of uniform_real_distribution class
    uniform_real_distribution<double> distribution(a, b);
    // Using b()
    cout << "Upper Bound: "
         << distribution.b() << endl;
    return 0;
Upper Bound: 20.5
